1. Goal. To provide guidance on the management of combat casualties who sustain blunt
abdominal trauma (BAT).
2.   Background.
     a. Unlike penetrating abdominal injuries where the decision to operate is relatively straight
        forward, those combat casualties that sustain blunt abdominal trauma offer more of a
        diagnostic and clinical challenge. With the improvements in body armor, truncal injury
        has decreased despite increasingly more lethal weapon systems. With the advent of
        Improvised Explosive Devices (IEDs), however, more casualties are presenting with
        evidence of BAT. While CT scans are available to assist the provider in decision making
        at a Level III facility, providers at far forward surgical units must decide to operate based
        on physical and Focused Abdominal Sonography in Trauma (FAST) exams.
     b. It is incumbent on the senior surgeon at each facility to ensure the staff understands their
        resource limitations and the inherent limitations associated with the use of the FAST
        exam to diagnose a hemoperitoneum. For those patients with a positive FAST,
        exploratory laparotomy should be undertaken immediately. Rarely, patients with a
        positive FAST and/or CT scan may be managed non-operatively if they are already at a
        Level III facility that can ensure adequate clinical follow-up and evaluation. DO NOT
        aeromedically evacuate patients out of the CENTCOM AOR who have a positive FAST
        exam and/or CT evidence of hemoperitoneum prior to completely assessing and
        controlling any and all ongoing intraabdominal hemorrhage. The benefits of non-
        operative management do not outweigh the risks of an in-flight hemorrhagic emergency
        with no potential for therapeutic surgical intervention.
     c. All grade III-V splenic injuries should undergo splenectomy due to the high failure
        rate of non-operative management with or without splenic embolization. Lacerated
        spleens of any grade with active hemorrhage encountered during laparotomy for any
        reason are best managed by splenectomy. In Level III facilities with Interventional
        Radiology capabilities, consideration may be given to embolization of grade 1/2 splenic
        injuries if the patient has NO other indication for exploratory laparotomy. These patients
        should be hemodynamically stable but with evidence of active bleeding or
        pseudoaneurysm and no evidence of hemoperitoneum on computed tomography. Ideally,
        these patients should be monitored in the MTF for up to 3 days prior to evacuation to
        another MTF. Additionally, the patient’s history should be discussed between the
        referring and accepting surgeons prior to evacuation. This is based on a literature review
        showing 99-100% success rate of non-operative management for grade 1/2 splenic

        injuries. Angiography and embolization for blunt injuries of other visceral organs may be
        used as an adjunctive procedure and should be determined on a case by case basis.
     d. Nothing in this CPG or Appendix precludes the use of exploratory laparotomy for BAT
        when either the clinical or tactical situation warrants.
3. Recommendations. See appendix A
4. Responsibilities. It is the trauma team leader’s responsibility to ensure familiarity and
appropriate compliance with this CPG.

Fast exam reliability is very operator dependent.

If angiographic embolization is to be attempted, the
patient should remain in the facility for a 3 day
observation period before being transported to                            Successful
another facility.
